摘　　要：结合北海神华电厂排水口深基坑工程实例,阐述围堰加钢板桩组合防渗止水体系组成的深基坑工程边坡稳定性、钢板桩稳定性、渗水量等计算,确定基坑边坡角度、钢板桩长度、围堰堰体大小。经过工程实例、模拟的理论数据与工程实测数据做对比分析,通过数据差异找出原因,为指导类似沿海深基坑工程提供很好的借鉴。实践证明,临海深基坑工程围堰加钢板桩止水体系在北海市神华电厂排水口工程中得到了很好的运用,极大地降低了施工成本,具有较好的安全性与经济性。This article combines the example of the deep-founded pit project of the Drainage Put of Beihai Shenhua Power Plant to explain the stability of the deep-founded pit project,the stability of the deep-founding pit project,the stability of the steel plate pile,and the amount of water seepage of the sideline project of the coffee weir with steel plate pile combination.The slope of the foundation pit,the length of the steel plate pile,and the size of the coffee weir body.After comparison analysis of engineering examples,simulated theoretical data and engineering measured data,find the cause through data differences,and provide a good reference for the guidance of similar coastal foundation pit projects.Practice has proved that deep foundation excavation cofferdam and steel plate pile stop water system in sea area has been well used in the drainage of the Shenhua Power Plant in Beihai City,and it greatly reduces the construction cost,which has good security and economy.
